The Star Trek: Voyager Companion describes B'Elanna as a young half-human half-Klingon in her twenties who is a member of the Maquis Rebellion.

When the episode aired, she called her parents to ask their opinions, and they replied, "You were good, but the girl that played that Klingon was really great!

[2] During season six, Dawson got the chance to explore B'Elanna's Klingon heritage thanks to an episode originally conceived by Ronald D. Moore for Star Trek: Deep Space Nine.

In the episode "Barge of the Dead", B'Elanna has a near-death experience and travels to Gre'thor, the Klingon Hell, where she meets her mother, Miral.

At the end of the series, Dawson described B'Elanna's character arc as that of an "unruly young woman who matures over the course of seven years.

She once attacked her schoolmate Daniel Byrd after he repeatedly taunted her, calling her "Miss Turtlehead" due to her cranial ridges.

Torres became associated with a Maquis captain named Chakotay and was serving as chief engineer on his ship, the Val Jean, when they were brought to the Delta Quadrant by "The Caretaker".

In 2371, B'Elanna Torres joined the Voyager crew with the rest of the Maquis from the Val Jean, as Captain Kathryn Janeway offers them the opportunity.

As the original chief engineer was killed during the trip to the Delta Quadrant, Captain Janeway promoted Torres to the position based on Chakotay's recommendation.

Over the first few months, Torres began respecting the captain and her decisions based on Janeway's strong leadership and their shared interest in science.

Torres becomes involved with a small group of officers who obtain the technology on the Sikarian black market and perpetrate a failed attempt to integrate it into Voyager's systems.

He believed the Klingon DNA had a specific biochemical property that could lead to a cure for the Phage, a disease affecting his people.

Later that year, Vulcan engineer Vorik triggered Torres's mating instincts when he forcibly initiated a telepathic bond with her while he is experiencing the pon farr.

During an incident in 2374, Torres confessed her love to him when they were left floating in space in environmental suits, with almost no hope of rescue ("Day of Honor").

Although Voyager was soon able to rescue them, Torres realized that her courage in admitting her love had brought her one step closer to discovering what she considered true honor.

Torres, remembering painful events from her own childhood, urged the Doctor to perform gene therapy to reduce this phenotype, and even went so far as to reprogram him to do so.

When Paris got her to open up, she admitted that she was afraid her husband would find living with two Klingons too difficult and leave her the way her father did.

Miral Paris, named after B'Elanna's mother, was born at the beginning of 2378, during Voyager's trip through a Borg transwarp conduit back to the Alpha Quadrant.

In an alternate timeline where Voyager made it home by different means, Miral was shown as an adult serving in Starfleet, with the rank of ensign.

Torres's birthdate—on September 2, 2014, the official Star Trek website published an archive article with information on the press release for the launch of the series.
